= Validation <validation>

We perform several validation tests to ensure the accuracy and reliability of our simulation results. This section details both code-level tests and scientific validations against established results.

- Comparison to THESAN

== Code validation
|
|
We ensure consistency of the updated BEoRN code with previous versions by running a series of simulations under identical conditions. We compare key outputs starting from the profiles of individuall sources, to the ionization maps, and finally to the global reionization signals. This step-by-step comparison allows us to identify any discrepancy that may arise from the code changes.

Similarly we maintain backward compatibility with the input format used in previous BEORN runs (i.e. snapshots generated by pkdgrav or 21cmfast). This allows us to reproduce the earlier runs and match the results as described by @Schaeffer_2023.

|
== Convergence tests
|
|
To ensure that our results are not sensitive to the numerical resolution of the simulation, we perform convergence tests. We compare the following variations of resolution: Firstly we compare effects of the grid resolution by running simulations with $128^3$, $256^3$, and $512^3$ cells. Secondly we investigate the impact of the mass resolution by comparing the results obtained from the #smallcaps[Thesan-Dark] 1 and 2 simulations, which have different particle masses, as mentioned in @procedure.
